GIT version doesn't compile with libmypaint (GIT version)

Hi,
4 days ago, mypaint_brush_stroke_to has been changed to take two additional parameters
float viewzoom, float viewrotation

This makes compilation of gimpmybrushcore.c fail.

What are the correct additional arguments to mypaint_brush_stroke_to ( 0.0, 0.0) ?

Many thanks for a hint, Helmut

The new arguments are viewzoom and viewrotation. Please either revert to libmypaint 1.3.0 or provide a patch for GIMP (it pobably won't be an easy one, for prerequisites it's likely to involve).

In my study
viewzoom : Effects speed-related parameters like Fine speed, Gross speed, Offset by speed.
viewrotation : Add this value to angles of elliptic dab and direction parameter, measured in radius. Seems to effect tilt too but I don't have a tilt-supporting tablet to test it.

From their names they seem to be used with canvas zooming and rotation. Since GIMP already calculates canvas zooming and rotation by itself, just set them as default values, which are viewzoom=1, viewrotation=0.

If you need a patch, here: https://drive.google.com/open?id=0ByvJcJmOQlkRNVVhREtneEZHYmc

The libmypaint master branch is supposed to be unstable right now, see

https://github.com/mypaint/libmypaint/issues/92

The best approach would likely be to let the libmypaint developers finish these changes and then check what needs to be changed for GIMP.

Michael
